Overview
The AD9066JR is a dual 6-bit, high-speed analog-to-digital converter (ADC) produced by Analog Devices Inc. This monolithic ADC is optimized for low-cost in-phase and quadrature (I and Q) demodulators, making it particularly suitable for applications such as digital direct broadcast satellite receivers where broadband quadrature phase shift keying (QPSK) modulation is used. The AD9066JR operates from a single +5V power supply and features CMOS-compatible digital outputs with a conversion rate of up to 60 MSPS.
